The Heart
This chamber of the heart receives deoxygenated blood from the systemic circulation
What is the right atrium?
3 factors that contribute to blood flow within the circulatory system.
What are cardiac output, resistance, and blood pressure?
The peak blood pressure generated when the heart's left ventricle contracts.
What is systolic?
Hormones that can increase blood pressure.
What are antidiuretic hormone, angiotensin ll, aldosterone, epinephrine and norepinephrine?
The 3 controls that regulate blood pressure.
What are neural, hormonal, and renal controls?
This chamber of the heart receives oxygenated blood from the lungs.
The volume of blood pumped out by the heart in 1 minute.
What is cardiac output?
Blood pressure when the ventricles relax and fill with blood.
What is diastolic?
This hormone causes vasoconstriction and increases blood volume by reducing water loss in the kidneys.
What is an antidiuretic hormone?
3 key factors that influence blood pressure homeostasis.
What are cardiac output, total peripheral resistance, and blood volume?
This chamber of the heart pumps oxygenated blood through the aorta, then travels through smaller arteries eventually reaching arterioles.
What is the left ventricle?
This is when blood pumped out of the heart through the arteries meets resistance in the arterioles.
What is total peripheral resistance (TPR)?
This happens because blood pressure is greatest in the arteries near the heart and decreases in peripheral vessels.
What is blood flows in 1 direction.
Hormone that causes vasoconstriction, increased blood volume, and triggers adrenal gland to secrete aldosterone.
What is angiotensin ll?
3 things that can cause an increase in blood pressure.
What are increase in cardiac output, an increase in total peripheral resistance, and an increase in blood volume.
This chamber of the heart pumps blood to the lungs where it reloads with oxygen before moving back to the heart and starting another circuit in the body.
What is the right ventricle?
The force exerted on the arterial wall by the blood inside.
What is blood pressure?
The average blood pressure in the arteries throughout the cardiac cycle.
What is mean arterial pressure (MAP)?
This type of hormone is a mineralocorticoid which regulates the concentrations of salt and potassium in extracellular fluids.
What is aldosterone?
Rather than directly influencing TPR and CO, like short term regulation, renal mechanisms alter this.
These types of blood vessels carry blood away from the heart and are designed to withstand high pressure.
What are arteries?
5 Liters
This is necessary to supply blood to all the tissue of the body to keep them functional.
What is a MAP of at least 60 mm Hg?
This hormone's primary function is to raise blood pressure. It attaches to mineralocorticoid receptors in certain organs, including the kidneys and colon, signaling them to increase the amount of sodium they send into the blood stream as well as the amount of potassium excreted in the urine. Increased sodium in the blood causes the body to retain water in the blood, increasing blood volume, which increased blood pressure.
What is aldosterone
Through this, neural, hormonal and renal mechanisms regulate blood volume, cardiac output and total peripheral resistance to maintain BP Homeostasis.
What are vasoconstriction or vasodilation?
