1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.
It has many different components within the cardiovascular system too, the main components include the heart, arteries, veins, capillaries and the blood. The heart is the key organ to the circulatory system. Its main function is to circulate oxygenated blood around the body and to deposit carbon dioxide into the lungs so it can be exhaled. The cardiovascular system works with a persons metabolism and are designed to do that in order to make sure the nutrient molecules are transported around the body to parts where they are needed. The Respiratory System The respiratory systems main function is to inhale oxygen and exhale carbon dioxide.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
Those that are affected include respiratory system, immune system, and nervous system. The respiratory system is a series of organs responsible for taking in oxygen and putting out carbon dioxide. The main organs in the respiratory system are the lungs. Your lungs are responsible for contracting and carrying out the exchanges of gases we breathe. It is extremely important that this systems functions properly.
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
The difference is internal respiration happens at the cellular level while external respiration is the actual breaths. 2. What are the key functions overall of the respiratory system? The key functions of the respiratory system is to bring air and blood into the alveolar air sacs so that the air can enter into the bloodstream while the carbon dioxide exits. It also maintains the body’s pH levels and body temperature.
It is produced through the breakdown of foods that we eat. It is then stored in our muscles, the only problem being it stores a small amount of ATP energy. For our bodies to keep producing the energy needed for an activity then ATP must be continually resythesised. To do this our body breaks down ATP using an enzyme so it becomes
It starts with oxygen poor blood being pumped from the right ventricle into the pulmonary trunk. The pulmonary trunk divides into right and left pulmonary arteries that subdivide into the lobar arteries in the lungs. The lobar arteries accompany the main bronchi into the lungs and then branches forming arterioles and then pulmonary capillaries that cling to alveoli. Here oxygen moves from the air sacs to the blood, and carbon dioxide from the blood moves to the air sacs. Next, the pulmonary capillary beds drain into venules which join to form two pulmonary veins exiting each lung.
Unit 5, Task 2- Gross structure of all main systems P3 Cardiovascular system- The main functions of this system are to transport nutrients, gases and waste products around the body, to protect the body from infection and blood loss, to help the body maintain a constant body temperature and to help maintain fluid balance within the body. The cardiovascular system works in conjunction with the respiratory system to deliver oxygen to the tissues of the body and remove carbon dioxide. Nutrients like glucose from digested carbohydrate are being delivered from the digestive tract to the muscles and organs that require them for energy. Hormones from endocrine glands are transported by the cardiovascular system to their target organs, and waste
The respiratory and circulatory systems work together to deliver oxygen to cells of the body (the lungs through air exchange, and the circulatory system by delivery of hemoglobin containing red cells to the capillaries where oxygen is released into the tissues) and removal of carbon dioxide. The circulatory system delivers nutrients absorbed through the walls of the small intestine to other organs (such as the liver, muscles, brain, heart), and delivers oxygenated blood to the digestive system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells.
