Circle True or False for the following questions.1. The heart beats without extrinsic stimulation from the autonomic nervous system. True or False 2. Autorhythmic cells are located only in the interventricular septum. True or False 3. Each heart chamber contracts separately, first the right atrium, then the right ventricle, left atrium, and left ventricle. True or False 4. The ECG records the electrical stimulation of cardiac muscle by the conduction system and not the contraction of the muscle itself. True or False 5. The normal pacemaker of the heart is the AV node. True or False
Can you kindly answer this?
PLEASE use in your own words and NOT outside sources just provide the answer itself in brief sentences THANK YOU!
1. When you stand up, gravity causes blood to pool in your legs and abdomen. This decreases arterial blood pressure because there's less blood circulating back to your heart, leading to a condition called orthostatic hypotension. Describe the baroreceptor reflexes in response to this drop in blood pressure. Be as specific as possible.

- Which of the following statements is false? Please encircle your answer and in each case, explain what is incorrect. When the muscular walls of the blood vessels all over a woman’s body contract, the space inside the vessels becomes larger so her blood pressure falls. Explanation: Hypertension during pregnancy reduces the blood supply from the endometrial arteries in the mother’s uterus to the fetus via the placenta. Explanation: Hypertension reduces the amount of amniotic fluid surrounding the fetus, because the blood flow to the baby’s kidneys is reduced so it makes less urine. Explanation: Fetal growth is not restricted in a pregnant woman with hypertension. Explanation:arrow_forwardMatch the following shunts with their location and function. Question 5 options: 123 this shunt carries oxygenated blood from the placenta away from the semifunctional liver towards the heart 123 this shunt connects the pulmonary artery with the aorta, further shunting blood away from the lungs 123 this shunt allows oxygenated blood in the right atrium to reach the left atrium, bypassing the lungs 1. ductus venosus 2. foramen ovale 3. ductus arteriosusarrow_forwardPatient : Mrs. So Mrs. So is a 28 year old visiting her OB in the 26th week of her pregnancy. She is experiencing varicose veins and swelling in her lower extremities. Her doctor explains that this is caused by the expanded uterus pressing on the large veins that run through the abdomen on their way up to the heart. Which pressure is altered in this case, and how is it causing edema?arrow_forward
