Endocrine System Is a group of specialized organs and body tissues that produce‚ store‚ and secrete chemical substances known as hormones. As the body’s chemical messengers‚ hormones transfer information and instructions from one set of cells to another. Because of the hormones they produce‚ endocrine organs have a great deal of influence over the body. Among their many jobs are regulating the body’s growth and development‚ controlling the function of various tissues‚ supporting pregnancy

information about humans’ circulatory system. One of the most important systems our body has if not THE most important since one of its organs is the heart. We will focus on senior citizens. As we age‚ our organs’ working mechanism becomes slower and our muscles tend to be less flexible or elastic and that is why we think the information we will provide‚ will be very useful. Some of the talking points will be: • General function of the system and how the organ system contributes to physiological homeostasis

Circulatory System Composition of Blood Red Cells -These are tiny‚ disc-like cells which do not have nuclei. -In their cytoplasm is the haemoglobin‚ a protein combined with iron. Haemoglobin combines with oxygen in places where there is a high concentration of oxygen‚ to form oxyhaemoglobin. -Oxyhagemoglobin is unstable compound. It breaks down and releases its oxygen in places where oxygen contentration is low. White Cells -They undergo a process of matruation and development in the

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

The Skeletal System 2/17/13 Period: 2 Sierra Smith Emily Johnson Imani Rigguns The skeletal system is one of the most important systems in the human anatomy. Without this system our bodies wouldn’t have any source of motion or movement. From the skull all the way to the toes of our feet‚ everything is important. Out of the 206 bones‚ they all form our different shapes and make us all unique. They create our framework and enables us the move and perform our different

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

Skeletal System and Muscular System In anatomy and physiology we study the structure of living things and the function of living systems. In physiology‚ the scientific method is applied to determine how different organisms‚ organ systems‚ organs‚ cells‚ and biomolecules carry out the chemical or physical function that they have in the living system. Both anatomy and physiology are subcategories of biology. Throughout our class we have discussed many different systems of the body. One system that is
