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). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
Plasma contains hormones, nutrients and waste substances. Red blood cells contain hemoglobin, an iron-containing protein that sticks to oxygen so it can be carried round the circulatory system. In high
BIOS255 BIOS 255 WEEK 5 Lab 5 - Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The primary functions of the lymphatic system are to drain and return interstitial fluid to the blood to absorb and return lipids from the digestive system to the blood, and to filter fluid of pathogens, damaged cells, cellular, and cancerous cells to help protect against invasion. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli.
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
Cardiovascular System: Blood Lab Report assistant Exercise 1: Observing Blood Questions A. What are the components of blood? Components of blood are: Red blood cells White blood cells Plasma and Platelets B. What is the function of red blood cells? The main function of red blood cell is to transport oxygen in blood to all cells of the body.
Homework : Chap 16 – odd questions & 18-22 (pg. 455) 1. Blood is defined as that _fluid__ which circulates through the __heart___ __arteries__ _veins___, and capillaries carrying nourishment, _electrolytes__ , _hormones___ , _vitamins___ , anti-bodies, heat and _oxygen__ to the body tissues, and taking away _waste__ _matter_ and _carbon_ _dioxide__ . 3. Blood spun in a centrifuge is composed of ____45_______ percent RBC and ___55______ percent plasma.
Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The lymphatic system helps fluids circulate the body and helps defend against agents that cause disease. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli.
Produces essential proteins and clotting factors for the blood and regulates metabolism and cholesterol. Gall Bladder – Stores bile secreted by liver. Bile is used to help dissolve fats in the small intestine. Pancreas – Functions both as an exocrine gland and an endocrine gland. Exocrine portion secretes digestive enzymes carried to the duodenum.
The right atrium receives deoxygenated blood via the superior and inferior vena cava. The blood then goes through the right ventricle and out to the lungs where it becomes oxygenated. The oxygenated blood then travels to the left atrium via the pulmonary veins, to the left ventricle, and then out to the rest of the body and organs through the aorta. The blood also supplies oxygen and nutrients to the heart via the coronary arteries that branch from the aorta. This pumping action of blood flow is controlled by electrical impulses in the heart.
It allows the cells to pass through. Then, it also where the process of exchanged between blood and lymphatic vessels occur. Due this process, it allows the lymphatic system to monitor the invading microbes. The lymphatic vessels also carry a clear fluid that it bathes in the body’s tissues that is known as lymph. Another organ is lymph node that is has specialized compartments where the immune system there and can encounter antigens.
