Answer:
The correct answer will be option C- endothelial cells of the endocardium.
Explanation:
The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.
This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.
Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.
Answer:
The nurse has taught the parents the following instructions:

Similarly mild soap also keep your skin soft and fresh as the ingredients like Aloe Vera, olive oil etc. The trimmed nails prevent you to make rashes on your skin because you can make new rashes on skin in the case of itching.
Answer: The appendicular skeleton is composed of 126 bones of the limbs and the pectoral.
Explanation:
Answer: True
The arteriovenous shunts can redirect blood through the skin to help regulate heat loss.
Answer:
The answer is- Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
Explanation:
The sympathetic nervous system (SNS) is a branch of the Autonomic Nervous System (ANS). Sympathetic Division of the ANS responds to threats- to fight or to run away. The stimulation of the sympathetic nervous system causes vasoconstriction of most blood vessels, including those of the digestive tract, skin and the kidneys.
It does the following;
- Increases the rate and strength of contraction of the heart
- Dilates the bronchioles of the lungs
- Decreases movement in the stomach and intestines (decreasing GI peristalsis)
- Increases the breakdown of glycogen and release of glucose from the liver thereby increasing blood glucose
- It dilates the pupil
- increases sweat secretion from the sweat glands
- constricts blood vessels of the skin
- Dilates blood vessel of the skeletal muscle
- Constricts blood vessels of internal organs except the heart and the lungs.
- Relaxes the muscle wall of the urinary bladder
- Stimulates hormone (epinephrine and norepinephrine) secretion from the adrenal medulla
NOTE: GI is Gastrointestinal tract
