Right ventricle: Receives blood from the right atrium ; pumps blood into the pulmonary artery.
Which vessel of the heart receives blood during right ventricular systole quizlet?
Which vessel(s) of the heart receive blood during right ventricular systole? Pulmonary trunk . Select the correct statement about the function of myocardial cells: 1 – Each cardiac muscle cell is innervated by a sympathetic nerve ending so that the nervous system can increase heart rate.

Which vessels directly receive blood during ventricular systole?
During ventricular systole, pressure rises in the ventricles, pumping blood into the pulmonary trunk from the right ventricle and into the aorta from the left ventricle.
Which blood vessels carry blood away from the heart?
The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
How does blood enter the heart?
Blood enters the heart through two large veins, the inferior and superior vena cava , emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
What causes damage to cardiac muscle if it is deprived of its normal blood supply?
The blood clot is the actual cause of the heart attack. If the blood and oxygen supply is cut off, muscle cells of the heart begin to suffer damage and start to die. Irreversible damage begins within 30 minutes of blockage. The result is heart muscle affected by the lack of oxygen no longer works as it should.
Which is the most significant source of blood flow resistance?
The correct answer is option (c) blood viscosity . Blood viscosity is the most significant source of blood flow resistance.
What is the source of ATP for cardiac muscle contraction?
The myocardium requires significant energy to contract continually over the human lifetime. These energy needs are met through mitochondria , myoglobins, and rich blood supply from the coronary arteries. The mitochondria generate ATP for the contraction of cardiomyocytes.
What’s the main artery called?
The largest artery is the aorta , the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
What marks the beginning of systole?
Isovolumetric ventricular contraction (a-b): This phase marks the beginning of systole and starts with the appearance of the QRS complex on the EKG and the closure of the AV valves at point (a).
Which small blood vessels distribute blood throughout the body?
Capillaries . Tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
What are the two arteries that carry blood away from the heart?
Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
Do all arteries carry blood away from the heart?
Arteries always carry blood away from the heart . Usually the blood is oxygenated; the exceptions are the pulmonary arteries, which carry blood away from the heart to the lungs to become oxygenated.
What are the 5 Major blood vessels?
- The vasculature works with the heart to supply the body with oxygen and nutrients and to remove waste products.
- There are five classes of blood vessels: arteries, arterioles, veins, venules and capillaries.
