Which of the following CORRECTLY describes the flow of lymph?
(a) Subclavian vein, Collecting duct, Lymphatic trunk, Lymphatic vessel, Lymphatic capillary
(b) Lymphatic capillary, Lymphatic vessel, Lymphatic trunk, Collecting duct, Subclavian vein
(c) Lymphatic vessel, Lymphatic capillary, Subclavian vein, Collecting duct, Lymphatic trunk
(d) Collecting duct, Lymphatic trunk, Lymphatic vessel, Lymphatic capillary, Subclavian vein
Answer:
The correct answer is option b.
Explanation:
The lymphatic pathway is a circuit where the lymphatic fluid is towards subclavian vein at the base of the neck. It is an open circulation pathway.
Body tissues have capillaries that reabsorb extra tissue fluid which is comes from blood plasma. Tissue fluid is move from lymphatic capillaries to lymphatic vessels, where lymph nodes filter the lymph.
It moves from lymphatic vessels into lymphatic trunks. Finally, it enters in collecting ducts and disposed into the subclavian veins at the base of the neck.
Thus, the correct answer is option b.
The correct order describing the flow of lymph is from the Lymphatic capillary, to the Lymphatic vessel, then to the Lymphatic trunk, Collecting duct, and finally the Subclavian vein.
Explanation:The flow of lymph in the body typically follows a specific pathway. As per the options provided, a correct representation of this lymphatic flow would be: (b) Lymphatic capillary, Lymphatic vessel, Lymphatic trunk, Collecting duct, Subclavian vein. The lymph fluid first enters small, blind-ended lymphatic capillaries. These capillaries then unite to form larger lymphatic vessels, which deliver lymph into the larger lymphatic trunks. The lymphatic trunks drain into two main collecting ducts, the thoracic duct and the right lymphatic duct, which in turn empty their contents into the subclavian veins, thus returning the lymph back into the circulatory system.

True of False: Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate.
Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
The amount of oxygen hemoglobin releases varies with the metabolic rates of tissues. High metabolic activity tissues receive more oxygen—as more oxygen molecules dissociate from the hemoglobin—than the less active ones.
Explanation:The statement that Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate is False. The oxygen-hemoglobin saturation/dissociation curve mechanisms regulate the amount of oxygen delivered to different tissues. Highly active tissues have high metabolic rates and therefore require more oxygen. Oxygen molecules dissociate from hemoglobin and enter these tissues due to the high difference in the partial pressure of oxygen between the tissues and the blood in the capillaries. Conversely, less active tissues like adipose tissues, which have lower metabolic rates, consume less oxygen. Hence, the partial pressure of oxygen within such tissues remains relatively high leading to fewer oxygen molecules dissociating from hemoglobin and entering the tissue interstitial fluid. Therefore, the amount of oxygen hemoglobin releases to tissues varies based on their metabolic rates.

The Brain stem area of the brain includes following 3 structures: ___________ for eye movement/walking; and ___________ to help regulate respiration and the _________________ that regulates heartbeat and breathing.
Answer:
The Brain stem area of the brain includes following 3 structures: mid brain for eye movement/walking; and pons to help regulate respiration and the medulla oblongata that regulates heartbeat and breathing.
Explanation:
The superior colliculi are the nuclei present in white matter of the midbrain and serve as visual reflex centers. These nuclei are involved in the coordination of eye movement when we follow a moving object.
The dopamine-releasing neurons present in the substantia nigra of midbrain regulate the body movement.
The cardiac center and respiration center (chemoreceptors) present in medulla regulate the heart rate and breathing rate respectively.
The pneumotaxic center of the pons is a nucleus involved in the regulation of inspiration and expiration during respiration and thereby regulate the rate of respiration.
Which of the following is a muscle for chewing (mastication)?
a. sternohyoid
b. orbicularis oris
c. scalenes
d. temporalis
Answer:
The muscles of the jaw consist of three muscles the Temporalis, Masseter and Pterygoid Muscles which work together to move the mandible at the Temporomandibular Joint.
Explanation:
Final answer:
The muscle responsible for chewing, among the given options, is the temporalis. The masseter is another major muscle for mastication. The sternohyoid, orbicularis oris, and scalenes have other functions like swallowing, moving lips, and assisting neck movement respectively.
Explanation:
Among the options provided, the temporalis muscle is the one that is responsible for chewing, also known as mastication. It is one of the chief muscles of mastication and is located in the temple. The temporalis muscle is attached to the lower jaw and when it contracts, it assists in closing the mouth by moving the mandible upward and backward.
In contrast to the temporalis, the masseter is another major muscle used for chewing because it elevates the mandible to close the mouth. This strong muscle is found in the cheek and plays a vital role in mastication. Both the temporalis and the masseter work together to exert the pressure necessary to bite and chew food before swallowing.
Kussmaul respirations are an indication that the body is
Answer:
Kussmaul respirations indicates the condition of acidosis and diabtetes ketoacidosis
Explanation:
Kussmaul respiration refers to the labored and deep breathing pattern. Adolph kussmaul introduced the term Kussmaul respiration.
This respiration refers to the form of hyperventilation in which the amount of carbon dioxide is decreased in the blood. The metabolic acidosis alters the normal pattern of breathing and results in rapid and shallow breathing. The Kussmaul respiration is most common in ketoacidosis.
Kussmaul respirations indicate the body's attempt to compensate for metabolic acidosis by hyperventilating to expel carbon dioxide and reduce acidity.
Explanation:Kussmaul respirations are a type of hyperventilation that is characteristically deep and labored. They are an indication that the body is compensating for metabolic acidosis, particularly when associated with diabetic ketoacidosis. In metabolic acidosis, the blood pH is low due to an excess of acid or a deficiency of bicarbonate. Kussmaul respirations occur as a respiratory compensation mechanism where the body attempts to correct this imbalance by exhaling more carbon dioxide (CO2), which is an acid when dissolved in the blood.
The increased respiratory rate and depth result from the body's need to lower blood acidity by releasing CO2. This compensatory mechanism can be observed in several conditions that cause metabolic acidosis, such as renal failure, and is often a serious sign that requires medical attention.

A) renal corpuscle
B) afferent arteriole
C) nephron loop (loop of Henle)
D) filtration membrane
E) juxtaglomerular complex
Answer:
E. juxtaglomerular complex
Explanation:
Macula densa cells are the columnar tubule cells. They are present in the wall of afferent arterioles. The modified fibers of smooth muscles present in the lining of the afferent arteriole are called juxtaglomerular cells.
The juxtaglomerular cells and macula densa cells together make the juxtaglomerular apparatus, also called juxtaglomerular complex. The function of the juxtaglomerular apparatus is to maintain the blood pressure of kidneys.
Answer:
The correct answer is E) juxtaglomerular complex
Explanation:
The smooth muscle cells of both the afferent and efferent arterioles are swollen and contain dark granules. These cells are called Juxtaglomerular cells. These cells secret Renin which convert angiotensinogen into angiotensin.
The epithelial cells of the distal convoluted tubules that comes in contact with the afferent and efferent arterioles are more dense than the other tubular cells and are collectively called muscula densa. The cells of the mascula densa may function as chemoreceptors; feeding information to the juxtaglomerular cells. The juxtaglomerular cells and macula densa together form juxtaglomerular complex.

Which graph BEST shows the relationship of kinetic energy (solid line) to potential energy (dotted line) as a hawk dives downward toward its prey and then returns to its original position in the air?
A) A
B) B
C) C
D) D
Answer:
b
Explanation:
hope im right
The kinetic and potential energy of the hawk as it dives and returns to its original position are inversely related, with one increasing as the other decreases.
Explanation:The relationship of kinetic energy (represented by a solid line) to potential energy (represented by a dotted line) as a hawk dives towards its prey and then returns to its original position in the air would be best shown by a graph in which the kinetic energy increases as the potential energy decreases, and vice versa.
As the hawk dives (loses altitude), its potential energy (height) decreases, but its kinetic energy (speed) increases. When the hawk returns to its original position (regains altitude), its kinetic energy decreases while its potential energy increases. Therefore, the kinetic and potential energies should be inversely related on the graph.

Mutations in DNA include deletions and insertions. These types of mutations:
A) Result in different amino acids to be read due to frame shifts
B) Result in segments of DNA being translocated in the genome
C) Increase the frequency of polyploidy
D) Always result in disease or harmful effects
e) All of these
Answer:
(A). Result in different amino acids to be read due to frame shifts
Explanation:
Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.
These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.
This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.
Thus, the correct answer is option (A).
