Heart Anatomy & Blood Flow
Blood leaving the right ventricle must pass through this before entering the Pulmonary Artery.
What is the Pulmonary Valve?
These tiny vessels have walls only one cell thick and are the main site of gas exchange.
What are capillaries?
This structure is considered the heart’s natural pacemaker.
What is the SA node?
This term means the amount of blood ejected by the left ventricle each time it contracts.
What is stroke volume?
Blood pressure is commonly measured at this artery in the upper arm.
What is the brachial artery?
This chamber receives deoxygenated blood returning from the body.
What is the right atrium?
This term describes the ratio of formed elements in the blood to the total volume of blood.
What is hematocrit?
How long do you count for an active heart rate accessment?
What is 10 seconds?
This term means the total amount of blood pumped by the heart each minute.
What is cardiac output?
This number represents the pressure when the ventricles are contracting.
What is systolic blood pressure?
This is the largest Blood Vessel in the Human Body and is the first place blood is ejected too outside of the heart.
What is the Aorta?
These blood vessels carry blood away tissues of the body.
What are veins?
This clinical term describes a resting heart rate that falls below 60 beats per minute in an adult.
What is bradycardia?
Complete the formula: Cardiac Output = ______ × Stroke Volume.
What is heart rate?
A normal systolic blood pressure is below this value according the standards observed in class.
What is (less than or equal too) 120 mmHg?
Put these four structures in order as blood leaves the lungs: left ventricle, pulmonary veins, Bicuspid valve, left atrium.
What are pulmonary veins → left atrium → mitral valve → left ventricle?
This protein carries oxygen and Carbon Dioxide in the blood.
What is hemogloblin?
You count 22 beats in 15 seconds. This is the person’s heart rate.
What is 88 bpm?
At rest, the approximate cardiac output of an average person is this value.
What is 5 L/min?
A person has a resting blood pressure of 134/89 mmHg. According to the exam categories, this is the classification.
What is Stage 1 hypertension?
Unlike most veins in the body, these four vessels carry oxygen-rich blood, transporting it from the lungs directly into the left atrium of the heart.
What are the pulmonary veins?
Put the following blood vessels in the correct order that blood travels through them, starting when blood leaves the heart and ending when it returns to the heart:
Aorta, arteries, arterioles, capillaries, venules, veins, superior/inferior vena cava
What is: Aorta → Arteries → Arterioles → Capillaries → Venules → Veins → Superior/Inferior Vena Cava?
Calculate traditional age-predicted HRmax for a 37-year-old.
What is 183 bpm?
A person has a HR of 80 bpm and a stroke volume of 70 mL/beat. Their cardiac output is this many liters per minute.
What is 5.6 L/min?
This vascular response occurs when smooth muscle in the walls of blood vessels relaxes, increasing vessel diameter and reducing peripheral resistance.
What is vasodilation?
