in some people, it doesn't, but usually, hemoglobin (red blood cells) carry oxygen throughout the body by passing through the lungs, receiving oxygen, and the heart pumps it throughout the body.
The cardiovascular system is how your heart pumps your blood throughout your body. Your excretory system is for removing waste materials from your body.
The heart, veins, arteries, capillaries, and the blood are the 5 main parts of the cardiovascular system.
The term cardiovascular refers to the heart (cardio) and the blood vessels (vascular). The cardiovascular system includes the heart, arteries, veins, arterioles, venules, and capillaries.
Oxygen-depleted venous blood travels to right atrium and ventricle of heart then into lungs for oxygenation then to left atrium and ventricle of the heart finally oxygenated blood is pumped throughout arteries to feed tissues and organs oxygen.
The cardiovascular system's primary purpose is to transport blood throughout the body, delivering oxygen and nutrients to tissues while removing carbon dioxide and waste products. It consists of the heart, blood vessels, and blood, working together to maintain homeostasis and support cellular functions. Additionally, the system plays a crucial role in regulating body temperature and facilitating the immune response. Overall, it is essential for sustaining life and health.
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
How the Heart and Circulatory system work.
how does a car lighting system work
The skeletal system is the organ system that works most closely with the muscular system.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
When a system does work on its surroundings, the sign of work is negative. This is because work done by the system involves energy leaving the system, which decreases its internal energy. In thermodynamics, this is typically represented as ( W < 0 ). Conversely, if work is done on the system by the surroundings, the work is considered positive.
