Skeleton of a diamondback rattlesnake Reptiles are a class of animals comprising turtlestuataraslizardssnakes and crocodiles. They are tetrapodsbut the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Their bones are better ossified and their skeletons stronger than those of amphibians.
May 17, 4 Comments Human Body Organ Systems The human body is made up of 11 organ systems that work with one another interdependantly.
These systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
We will briefly discuss the major functions of each organ system below. Integumentary system— skin, hair, nails Forms the external body covering and protects deeper tissues from injury. Houses cutaneous receptors, sweat glands, oil glands, and synthesizes vitamin D.
Provides a framework muscles use movement. Bones also store minerals and create blood cells. Muscular system— skeletal muscles Maintains posture and produces movement locomotion.
Lymphatic system— red bone marrow, thymus, lymphatic vessels, thoracic duct, spleen, lymph nodes Houses white blood cells lymphocytes involved in immunity.
Returns leaked fluid from blood vessels to the blood and disposes debris within the lymphatic stream. Respiratory system— nasal cavity, pharynx, larynx, trachea, bronchus, lung Removes carbon dioxide and continually supplies blood with oxygen.
Gaseous exchanges occur in the respiratory system lungs. Digestive system— oral cavity, esophagus, liver, stomach, small intestine, large intestine, rectum, anus Breaks down food to be absorbed and eliminates indigestible waste.
Nervous system— brain, spinal cord, nerves Control system of the body, responds to internal and external changes, activates muscles and glands.
Endocrine system— pineal gland, pituitary gland, thyroid gland, thymus, adrenal gland, pancreas, ovary, testis Glands from the endocrine system secrete hormones that regulate many processes like growth, metabolism, and reproduction.
Cardiovascular system— heart, blood vessels The heart pumps blood and blood vessels transport it. Blood carries oxygen, carbon dioxide, nutrients, waste and more throughout the body.
Urinary system— kidney, ureter, urinary bladder, urethra Eliminates nitrogenous wastes from the body. Sex hormone and sperm are produced by the male testes. Male ducts and glands help deliver the sperm. Ovaries produce female sex hormones and eggs. Other female reproductive structures serve as sites of fertilization and development.
For instance, the mammary glands produce milk for the newborn.Human Anatomy & Physiology - caninariojana.com (34 reviews). Welcome to caninariojana.com, a free educational resource for learning about human anatomy and physiology.
