Arteries
Arteries are elastic vessels that transport blood away from the heart. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. Systemic arteries deliver blood to the rest of the body.
Veins
Veins are elastic vessels that transport blood to the heart. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins.
Capillaries
Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. Fluid and gas exchange between capillaries and body tissues takes place at capillary beds.
Sinusoids
Sinusoids are extremely small vessels located within the liver, spleen, and bone marrow.
Arterioles
a small diameter blood vessel that branches out from an artery to a capillary
Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.

What is resting heart rate?</h3>
Resting heart rate (RHR) is the average number of beats your heart makes per minute. Your RHR may be impacted if you have a diagnosed heart issue because of things like your medications and the nature of your condition.
The range of a normal resting heart rate (RHR) is 60 to 100 beats per minute (bpm).
If your RHR is regularly over 100 beats per minute, you have tachycardia, and you should consult a doctor, especially if you also experience additional symptoms like tightness in your chest, exhaustion, or shortness of breath.
