The blood consists of two major portions: blood cells and plasma. The functions of the cardiovascular system: the cardiovascular system is so important to our body, that if it stops for a minute, rapid death will occur. The flow of blood is necessary for existence of life. If the flow of blood stopped, life will stop. Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes).
The process of respiration involves the energy that is released from the food and the cells require good supplies of nutrients and oxygen in order to release a great deal of energy. The heart which is the most crucial organ in the circulatory system is a muscular pump that produces blood pressure to push the blood through the arteries and around the body; however the mammalian heart is a muscular double pump. The reason why it’s called a ‘double pump’ is because the right side pumps deoxygenated blood to the lungs to be oxygenated and the left side pumps oxygenated blood to the rest of the body. In addition to this, the left and right side of
Why is it important for organisms to regulate internal temperatures or metabolic processes at different temperatures? -Certain vital enzymes will become inactive if the temperature is too cold, and denatured if the temperature is too hot. The organism cannot function without these vital enzymes. 8. Explain how the process of blanching is used in the food industry and why a specific temperature is required.
Thermoregulation is controlled by the hypothalamus, using two sets of thermo receptors one set in the hypothalamus, these measure the temperature of the blood passing the brain (core temperature) and the other based in the skin to measure the external temperature both are needed for the body to make adjustments accordingly to maintain the body temperature. When the body temperature has decreased due to cold environments of the organism the change in
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
* Water freezes at zero degrees Celsius. * Water vaporizes at a hundred degrees Celsius. Myths about Water - Drinking water will reduce blood alcohol level in your body. MYTH!
This is important because if your body gets too cold your cells can’t maintain cellular function and would become denatured. The optimum temperature for the body is 37 degrees Celsius so is your temperature drops below temperature it won’t be able to function at a healthy level. This is known as hypothermia. Hypothermia can also put the body at risk. If the body rises above the optimum temperature your cells cannot maintain healthy cellular function and would become denatured.
According to our practice, on admission to Recovery, patients’ temperature is in most of the cases below 36 degree Celsius. Often they are shivering and complaining of feeling cold, thus extra warming blankets need to be applied and increase volume of oxygen is necessary (Stoelting: 2007). Some patients will complain of pain, therefore administration of analgesia is required. All this additional postoperative care will prolong the time spent in Recovery area. According to National Institute for Health and Clinical Excellence (NICE: 2008) hypothermia is a temperature below 36 degree Celsius.
If the blood temperature falls, it stimulates a ‘heat loss’ centre in the brain which sends impulse to the skin, causing vasoconstriction and the cessation of sweating. These changes reduce heat loss from the skin. Temperature regulation The human body is able to regulate its own internal temperature. It is important that we keep out internal temperature between 37 and 38 degrees. This is important as everything in the body has a prime temperature it works at.
With human deaths constantly on the rise, animal testing should be used as our primary source for cures. As many people may think animal testing has not just started recently. The idea of stewardship of animals developed in ancient times, as early as humans domesticated animals. Additionally in early cultures, priests or shaman began to observe the relationship between human health and animal diseases. Many basic cell processes are the same in all animals, and the bodies of animals are like humans in the way that they perform many vital functions such as breathing, digestion, movement, sight, hearing and reproduction.
