    Explain how the two parts of the nervous system work together Central Nervous System and Peripheral Nervous System
    The PNS carries impulses in and out of the CNS
    Identify the major parts of the brain
    Cerebrum(remembering, thinking, feeling), Cerebellum(coordination, balance), brain stem(breathing, digestion, heart rate)
    Describe the structure and function of the central and peripheral nervous systems CNS: made up of the brain and spinal cord. it processes information, creates a response, and delivers it to the body part PNS: made up of of neurons and other cells and it carries impulses to and from the central nervous system

    Explain the connection between the nervous system and the endocrine system They both work together to maintain homeostasis, development and reproduction. They both communicate with the body and help it function

    Lesson 7.02: Respiratory and Circulatory Systems
    Explain how the respiratory and circulatory systems work together The Respitory system gets oxygen into the Circulatory system that takes the Oxygen, through the blood stream, to other parts of the body.

    Describe the structures and functions of the respiratory system Organs like the lungs, the throat, and the passageways in between function to take in oxygen and put out carbon dioxide
    Describe the structures and functions of the circulatory system It circulates nutrients and oxygen and removes CO2 and it is made up of the heart which powers the whole process like with veins, arteries and capillaries.

    Differentiate between systolic and diastolic blood pressure In Systolic pressure blood flows from the heart to arteries. In Diastolic pressure the heart relaxes and blood to flows back to the heart.

    Describe the effects of lifestyle on the respiratory and circulatory systems
    Smoking especially effects the repertory and circulatory systems because it can raise blood pressure and heart rate and reduce the blood flow to like fingers and toes Lesson 7.03: Digestive and Excretory Systems

    Describe the structures and functions of the digestive system The digestive system starts in the mouth then goes through the esophigous then to the stomach where digestive fluids break down food and passes it on to the intestines to absorb the nutrients

    Describe the structures and functions of the excretory system excretory system functions to remove waste from the human body. The kidneys remove waste from the bloodstream when producing urine and the bladder collects the urine for disposal Lesson 7.04: Muscular, Skeletal, and Integumentary Systems

    Describe the structure and functions of the skeletal system The skeletal system is made up of the body’s bones, which is basically a frame of support for the body, as well as, like in the skull and ribs, protect more fragile parts of the body. And bones line the phemur and other leg bones help us be able to stand and run

    Describe the structure and functions of the muscular system The muscular system helps us to move and helps us have posture and helps maintain body temperature and pump blood throughout the body
    Explain how the muscular and skeletal systems work together The skeleton is like a frame and the muscles attach to that frame though the tendons and when we flex our muscles it helps us move our frame

    Explain that the largest organ in the body is also the body first line of defense against pathogens Well the largest organ is the skin, and it is in first line because the ouside world comes into contact with the skin first, and the epidermis protects what is underneath and the pathogens cannot penetrate the skin easily Lesson 7.05: Reproductive System

    Describe the structure and functions of the male reproductive system Well
    the main aspect of the male reproductive system is the sperm, which is stored in the testes. The sperm is what fertilizes the woman’s eggs, causing her to get pregnant. Mainly, what all the other things like prostate gland and urethra do is transport the sperm

    Describe the structure and functions of the female reproductive system Like how the sperm is the main aspect of reproduction in men, the eggs are the main aspect in women. . The ovaries develop and release eggs. The urutus and cervix are where the baby developes during pregnancy.

    Describe fertilization
    Well men have sperm to firtilize the womans eggs and the sperm is stored in the testes and the eggs are stored in the ovaries After sex, where the man releases the sperm, the sperm and egg meet in the womans fallopian tubes for fertilization

    Describe development following implantation
    After implantation, after 8 weeks the embryo develops into a fetus Lesson 7.06: Immune System
    Identify the body systems that protect from pathogens
    The skin protects against pathogens by not easily allowing them to enter the body. Mucus also helps by stopping pathogens entering the nose during breathing. Digestive system also helps because sometimes pathogens cant survive because of acid

    Summarize how the cells of the immune system respond to pathogens When pathogens enter the body and destroy cells, it triggers blood flow to the area, where white blood cells fight the pathogen
    Identify methods used to control pathogens
    Washing hands is a good way because many pathogens cant make it past the skin, so usually the only way in the body is through our mouth and eyes so if your wash your hands you can avoid allowing pathogens to enter your body if your touch your eye or mouth

    Explain how vaccines artificially produce acquired immunity Vaccines
    slightly expose you to the pathogen to teach your immune system to fight it off and then it is no longer a problem when you are exposed to if full on
