The circulatory system (also known as the cardiovascular system) is a network of organs and tissues present in the human body and is vital for life. It uses blood to transport gases, nutrients, hormones, immune cells and heat around the body and removes waste from the body. The circulatory system is made up of the heart, lungs, arteries, veins and capillaries, all of which work in unison to transport blood throughout the body. Say no to plagiarism.

Get the original essay Cellular respiration is a process by which the body's cells break down sugars into a form of energy (ATP stores) which can be used by the muscles of the body. body. The process requires oxygen, and when muscles contract and use energy, one of the main waste products created is carbon dioxide. The circulatory system collects oxygen from the alveoli of the lungs and delivers it to body tissues so that cellular respiration can be carried out and returns deoxygenated blood (oxygen is used in cellular respiration) to the heart so that it can be pumped towards the lungs. again for oxygenation. Throughout physical exercise, cellular respiration is the common process of transforming sugar into a form that the cell can use for energy. Cellular respiration takes in food and uses it to create ATP (adenosine triphosphate), a chemical that the cell uses as an energy source. Usually this method requires oxygen and is generally known as aerobic respiration, the equation for cellular respiration is glucose + oxygen. The term homeostasis refers to the tendency towards a relatively stable balance between interdependent elements, maintained by physiological processes, because the endocrine system plays an important role in homeostasis, because hormones must regulate the activity of the body's cells, i.e. that is, the release of hormones in the body. blood is controlled by a stimulus. During homeostasis, the body increases sweat production, heart and respiratory rate, to maintain a healthy homeostatic system. Homeostasis depends on the body's ability to detect or oppose these changes. Through proper exercises (jumping jacks), it is evident that there is an obvious increase in physical activity, as the muscle cells breathe more than when the body is at rest. As the heart rate increases during exercise, the frequency and depth of breathing also increases, ensuring that more oxygen is absorbed into the bloodstream and more dioxide carbon is eliminated from the body. Additionally, capillaries enable gaseous exchange of oxygen and carbon dioxide because they surround the alveoli and have thin single-cell walls that facilitate the process of gas diffusion. When blood arrives in the alveoli with a higher concentration of CO2 and a lower concentration of oxygen (produced by cellular respiration), it diffuses through the capillaries with the alveolar air, which has a much lower concentration of CO2 and a higher oxygen concentration. This means that there is a concentration gradient that allows CO2 to diffuse out of the blood and into the alveolar air. Due to the higher oxygen concentration of the alveolar air, oxygen diffuses into the blood through capillaries and combines with hemoglobin in red blood cells to form oxyhemoglobin. The blood is now rich in oxygen and..
