The fifth grade health curriculum focuses on the anatomy and physiology of the Digestive system, Circulatory system, Respiratory system, Reproductive systems and Immune system. This specialized tissue is composed of a liquid matrix called plasma, where highly differentiated cells are suspended. A major unit in third grade is the exploration of the Skeletal System. There are a wide variety of topics covered in health class all of which are related to the Pennsylvania State Academic Standards. The circulatory facilitates the movement and delivery of oxygen, water and nutrients to the body's cells. These five bones are found in the lower back. Hillendale Health How far does your cough travel? These tubular structures are classified into three types: veins, arteries and capillaries.
Muscular System Different types of muscles enable motion, generate heat to maintain body temperature, move food through digestive tract and contract the heart. These 12 bones are found in the upper back. Both sides have an atrium and a ventricle. The are five bones found in the middle area of the hand. They would also have an irregular pulse, have difficulty sleeping, and feel a greater need to urinate at night eMedicine 2007. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning. This is how oxygen can enter the bloodstream, and how carbon dioxide can leave.
An adult has about 5 quarts. We call our platelet plugs scabs. Digestive System The digestive system stores and digests foods, transfers nutrients to the body, eliminates waste and absorbs water. Nutritive components of food are also absorbed into the bloodstream via the capillary walls and circulated throughout the body. It carries nutrients, oxygen and water to different cells in the body and removes wastes the cells create. They are involved in the process of gas exchange between the alveoli and blood.
The heart is found slightly to the left at the center of the chest, and it is primarily responsible for pumping blood and keeping the blood moving throughout the body, explains Hillendale Health. The right atrium and right ventricle receive deoxygenated blood returning back to the heart from all over the body. It pumps blood through the blood vessels of the organism, enabling oxygenated blood to reach cells, and deoxygenated blood to return to the lungs, where gas exchange occurs. S National Library of Medicine. Alveoli The epithelial tissue is made up of closely packed cells and has one or multiple layers. Engaging in regular aerobic exercise helps make the heart stronger.
The heart is covered by a protective sac called the pericardium Maton et. Nutrition education is the first unit of study in fourth grade. It is an amazing highway that travels through your entire body connecting all your body cells. There are over 480 million alveoli in the average lung. Fluid passing through that hose exerts more pressure on the hose walls and threatens to rupture the hose.
When the platelet plug is completely formed the wound stops bleeding. The skin is an organ of the immune system that keeps harmful substances out of the body and holds beneficial substances in. Blood is a substance that constantly flows throughout the body, and it is pumped by the heart. It consists of the bones that make up the arms and legs, as well as the bones that attach them to the axial skeleton. The main parts of the circulatory system are the heart, blood, and blood vessels. The most important organs of the excretory system are the kidney, liver and skin. This is so that the right atrium can collect the deoxygenated blood and pass it through the heart which pumps it by the right ventricle to the lungs to be oxygenated once more Maton et.
Urinary System The urinary system eliminates waste products and maintains water balance and chemical balance. A gland is a bunch of cells that release chemicals. The pericardium itself is composed of two parts. The main organ in the circulatory system is the heart, according to Hillendale Health. This is because it is harder to pump blood to the rest of the body than to just pump it to the lungs and back Maton et. Test your knowledge and learn more as you go via a series of respiratory system quizzes at.
Cancers of the blood cells produced by bone, such as or , are more common. The body needs oxygen to live. Hence, thicker muscle means that the left ventricle is more powerful in pumping blood than the right ventricle. Furthermore, the system is also responsible for carrying some of the wastes from the cells such as carbon dioxide, away from the cells to be expelled by the body Delos Johnson, 2006. The heart pumps blood inside the lungs and takes in oxygen and releases carbon dioxide.
As the heart beats in the chest, it pushes blood out through arteries to nourish cells with oxygen and nutrients. Immune System The immune system is made up of cells, organs, proteins and tissues that fight together to guard the human body against diseases. Cardiovascular System The cardiovascular system delivers oxygen, hormones, nutrients and white blood cells around the body by pumping blood, and it removes waste products. The legs, on the other hand, support and bear the weight of the upper body while a person stands. The heart beats three billion times in an average life span and its primary goal is keeping the blood flowing through the body. Human anatomy is important to study to help explain how organs and other structures of the body work.
Next we investigate how the muscular system and nervous system function and how to keep those systems working at their best. The male skeleton is usually longer and has a high bone mass. They help to protect your brain. Muscles attach to bones through tendons. The plasma carries the blood cells and other components throughout the body. People suffering from this disease are easily fatigued due to the excessive work that the heart is coping with from the increased blood pressure eMedicine, 2007.
