What is the function of collenchyma?Provides structural support to growing tissuesDo collenchyma cells contain cytoplasm? Nucleus?Yes. They contain cytoplasm and nucleus.Do sclerenchyma contain cytoplasm? A nucleus?No.what is the function of sclerenchyma?structural supportWhat is a sclereid?Sclerenchyma cells that are different from fibers in a way that they vary in shape. Fibers are elongated cellsXylemvascular tissue that carries water upward from the roots to every part of a planttracheidsA water-conducting and supportive element of xylem composed of long, thin cells with tapered ends and walls hardened with lignin.vessel elementsA short, wide, water conducting cell found in the xylem of most angiosperms and a few nonflowering vascular plants. Dead at maturity, vessel elements are aligned end to form micropipes called vessels.PhloemLiving vascular tissue that carries sugar and organic substances throughout a plantsieve tube elementsfound in phloem; stacked end to end; have holes so materials can get in and out of the phloemCompanion Cells (Phloem)Cells adjacent to the sieve elements of the phloem tube which perform some of the metabolic functions of the sieve elements and provide energy for active transportDo phloem cells contain cytoplasm and/or a nucleus at functional maturity?Sieve tube elements do not contain a nucleus, but contain cytoplasm.what is function of root hairs?absorb water and mineralsTab rootRoot that grows underground. Have only primary root that stays for length of plant and as deep feederfibrous rootsGrows underground, and present in cluster of small same-sized roots. Primary root is replaced by adventitious root.Adventitious rootsroots that arise above groundhow do the villi and microvilli relate to the intestine's function?They increase surface area for nutrient absorption.What is the functional unit of kidney?nephronEsophagustransports food to stomachtracheaa large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.salivary glandsGlands of the mouth that produce saliva, a digestive secretionliversecretion of bile (important for lipid digestion), storage of nutrients, many other vital functionsGallbladderStore & concentrate bile produced by the liver until it is needed in the small intestinepancreassecretes insulin and glucagonspleenAn organ that is part of the lymphatic system; it produces lymphocytes, filters the blood, stores blood cells, and destroys old blood cells.thyroid glandproduces hormones that regulate metabolism, body heat, and bone growththymusAn immune organ located near the heart. THe thymus is the site of T cell maturation and is larger in children and adolescents.Follow of blood through the nephron from glomerulus?Glomerulus -> proximal convoluted tubule -> Descending limb -> Ascending limb -> Distal convoluted tubule -> Collecting ductPathway that eggs take to leave the female bodyovaries -> fallopian tubes -> uterus -> cervix -> vagina (menstrual cycle)Pathway that sperm takes to leave the male bodytestes -> epididymis -> Ductus deferens -> seminal vesicles -> urethrafemale gonadsmale gonadsnormal blood pressureless than 120/80 mmHgPrehypertension120-139/80-89 mmHghigh blood pressure140/90 or abovehypotensionless than 90/60systolic pressureBlood pressure in the arteries during contraction of the ventricles. Blood pressure is at the highestdiastolic pressureoccurs when the ventricles are relaxed; the lowest pressure against the walls of an arteryWhere does gas exchange occur for fetal pigs?Gas exchange occurs in mothers' placenta. The umbilical artery carries oxygenated bloodBlood pathway from the lungs and going to the kidney?1. lungs 2. pulmonary veins 3. left atrium 4. bicuspid valve 5. left ventricle 6. aortic semilunar valve 7. aorta 8. descending aorta 9. renal arteryBlood pathway from right atrium and going to the head?1. R Atrium 2. tricuspid Val 3. R ventricle 4. Pulmonary semilunar val 5. pulmonary trunk 6. R/L pulmonary artery 7. R/L pulmonary capillaries lungs 8. R/L pulmonary veins 9. L atrium 10. Bicuspid val. 11. L ventricle 12. Aortic semilunar val. 12 Aorta 13. R/L common carotid arteryBlood pathway from liver going to the left ventricle?1. R/L Hepatic vein 2. Inferior vena cava 3. R atrium 4. Tricuspid val 5. Pulmonary semilunar Val 6. Pulmonary trunk 7. R/L pulmonary artery 8. Lungs capillaries 9. R/L Pulmonary veins 10. L atrium 11. Bicuspid val 12.
