B.10(A) Readiness
Circulatory System
Heart, Arteries and Veins
Arteries flow away from the heart
Veins flow toward the heart
Circulates blood throughout the body
Nervous System
Brain, Spinal cord, and nerves
Network of nerve cells that transmit impulses between parts of the body
Stimulus and Response
Respiratory System
Nose, Nasal cavity, Trachea, Lungs
Gas exchange- Taking in oxygen and expelling carbon dioxide
Animal Reproductive System
Female- Ovaries, Uterus, and Vagina
Female produces egg as reproductive cell/gamete. (haploid cell)
Male- Prostate, Testis, Urethra, Penis
Males produce sperm as reproductive cell /gamete. ( haploid cell)
Fertilization - the union of sperm and egg to create zygote (the first diploid cell).
Excretory system
Kidneys and bladder
Kidneys remove excess water and waste from the blood to maintain homeostasis.
Sweat glands in the skin secrete a fluid waste, its primary functions are temperature control
Endocrine System
Thyroid, Pituitary gland, Pancreas , Adrenal gland
Regulates Hormones for metabolism, growth, digestion and response
Integumentary System
Skin (epidermis)
Protects the body from various damage, water loss, and outside invaders
Muscular System
Muscles- skeletal, smooth, and cardiac
Helps with movement, maintaining posture, digestion and circulation of blood throughout the body
Skeletal System
Bones and joints
Allows attachment points for muscles to move at joints. Maintain posture and framework of the body.
The bone marrow produces blood cells.
Digestive system
Mouth, Esophagus, Stomach, Intestines, Colon, Anus
Break down of food molecules (carbohydrates, proteins , lipids)
Immune System
Lymph Nodes, Lymphatic tissue
Defend the body against foreign invaders like bacteria, parasites, viruses, and fungi.
