Summary Circulatory System The circulatory system is made up of the heart, blood and blood vessels known as arteries, capillaries and veins. The heart pumps blood throughout your body through the blood vessels. Blood delivers oxygen and nutrients to cells and carries away carbon dioxide and other waste materials. The heart looks like an upside-down pear. It is about the size of your closed fist. It is almost in the middle of your chest. The heart is made of muscle divided into four parts

food into the bloodstream. Then, the blood delivers the nutrients to the rest of the body and this is the circulatory system. Cells get energy from the nutrients. So, once the food breaks down we get the nutrients and the nutrients travel through the whole body in the circulatory system. Then when the nutrients reach the cells in our leg muscles then the cells get energy. For the circulatory system to work it requires the heart, lungs, arteries and veins. The heart pumps blood into our body. The

1. Describe the four basic human body structure units and their functions The four basic human body structures and their units are as follows – • Cells • Tissues • Organs • Systems Cells A cell is the simplest and smallest unit of the human body. They can live independently and can also reproduce themselves. Cells exist in a variety of shapes and sizes including elongated, oval and square. Cells have many different functions. A group of cells is called a tissue. The

in the human body. These systems include the circulatory system, respiratory system, immune system, skeletal system, excretory system, urinary system, muscular system, endocrine system, digestive system, nervous system and the reproductive system. I will give the basics on each system. The circulatory system includes the heart and blood vessels. It pumps blood to the body which sends oxygen to the cells and takes away waste. The respiratory system includes the nose, trachea and lungs and

There tongues are used to catch prey but humans use them to talk. This is how the frogs and the humans digestive system are alike and not alike. Respiratory systems: Some similarities between the frog and the human in the respiratory system is both systems bring oxygen to the body and removes carbon dioxide. The main organ is the lungs in the respiratory system, for both humans and frogs. Some differences are the frog lacks muscles the human have. Human use lungs to breath frogs use mostly there

parts of the body. This system has full control over all other systems. * Cardio Vascular/Circulatory system The cardio vascular system is a network made up of the heart, blood, blood vessels, arteries and veins. This system moves blood, nutrients, hormones, oxygen and carbon dioxide around the body. It also gets rid of wastes that needs to be disposed of. * Respiratory system The respiratory system consists of the trachea, the lungs and the diaphragm. This system is where oxygen is taken

Germany 2Department of Philosophy, University at Buffalo, Buffalo, NY, USA Abstract. The human body as conceived by medical science is a system made of systems. The body is divided into bodily systems proper, such as the endocrine and circulatory systems. These are subdivded into many subsystems at a variety of levels whereby all systems and subsystems engage in massive causal interaction with other systems and subsystems. In this essay we offer an explicit definition of bodily system, and
